angularCompiler.getNextProgram is not a function, angular 12 & custom-webpack

Question

I've just update my angular 11 project to 12.
I'm using @angular-builders/custom-webpack package in my devDependencies and using the following command to build my angular project.

ng build --configuration=production --build-optimizer --optimization

but after updating to angular 12, I'm getting the following error:

Error: ./src/main.ts
Module build failed (from ./node_modules/@angular-builders/custom-webpack/node_modules/@angular-devkit/build-angular/node_modules/@ngtools/webpack/src/ivy/index.js):
TypeError: angularCompiler.getNextProgram is not a function

    at processTicksAndRejections (internal/process/task_queues.js:97:5)

I'm using the following package:

"@angular-builders/custom-webpack": "^11.1.1"

Answer 1

The problem was gone with installing version 12 of @angular-builders/custom-webpack
nowadays 12.0.0-beta.0

@angular-builders/custom-webpack@12.0.0-beta.0
